1.2. Development Tools
The development tools provided must be installed and run on a PC with a GNU/Linux Operating system (e.g. Debian,
Ubuntu or Redhat distributions). The GCC toolchain provided creates executable binaries that can be run on the
EB2410ITX. This toolchain is also required to build the kernel and Embedded Linux. Full details of building Linux are
provided on the EB2410ITX resources page.
In order to run the development tools the host PC requires:
• 500MHz or faster processor
• Installed GNU/Linux distribution
• 128MB RAM
• 1GB of hard disk space (3GB if building Embedded Linux)
• CD-ROM Drive
In addition to the development tools, the module usually requires serial communications to access its bootloader and
booted system. Most modern PC have serial ports, however increasingly only USB ports are provided, most typical USB>Serial converters appear to work with the EB2410ITX.
1.3. Using the development board
The EB2410ITX is a complete system. With the addition of a suitable power supply and PC the Kit provides everything
required to start producing the desired solution. The ABLE bootloader allows a flexible use of the EB2410ITX. ABLE can
start Linux images from a variety of sources including the network. In this mode of usage the serial port is used as a console to communicate with the device.
1.4. Handling precautions
This development board is intended for use either within a workshop/laboratory environment or as an integrator solution

Handling precautions
within a larger product. Because of this the EB2410ITX board is supplied without an enclosure. The lack of an enclosure
means that standard electrostatic control procedures should be used when handling the board. When using the EB2410ITX
outside an enclosure the following is recommended:
• Only hold the board by the edges
• Always use proper static handling equipment, as a minimum an earth strap

2.1. Overview
The EB2410ITX is a complete system that includes a large number of Input/Output facilities. Simtec Electronics provide a
number of application notes accessible via the EB2410ITX resources page or on the supplied CD-ROM which demonstrate the use of the board.
Figure 2.1. Detailed block diagram of the EB2410ITX
2.2. Samsung S3C2410 SOC
The S3C2410 is a 272 ball fine pitch Ball Grid Array (BGA) device from Samsung. The large number of peripherals within the device give flexibility to the user and the ability to use numerous I/O solutions without additional controllers. The
S3C2410 has a full MMU and high bandwidth memory system allowing a range of standard operating systems to be run.
The S3C2410 has a Harvard architecture 16KByte Data/16KByte instruction cache which further improves performance.
The power management systems within the SOC allow for very flexible power control and with a typical power usage of
0.3W at 266MHz operating speeds contributes towards the EB2410ITX low overall power consumption.
Simtec provide Debian GNU/Linux as standard which provides a full development environment identical in look and feel
to an x86 install of Debian GNU/Linux.
The large number of peripherals and interfaces are summarised as follows:
• ARM920T 32-bit RISC CPU
• 32-bit mode (ARM) and/or 16-bit mode (Thumb)
5

For further details on the S3C2410 please consult the Samsung S3C2410 User manual [http://www.samsung.com/Products/Semiconductor/SystemLSI/MobileSolutions/MobileASSP/MobileComputing/S3C2410/
S3C2410.htm]
2.3. Serial ports
The S3C2410 has three serial ports complete with FIFO. The first port is used as a console port by the bootloader and
Linux.
There is an optional super I/O controller which provides an additional two serial ports.
There are two ports which are buffered and level translated to RS232 signal levels. The first is an external 9way D port
(PL1) and the second is a ten way box header (PL7).
The ports output through the level converters may be selected from any of the five available sources by using the jumper
matrix (LK2 to LK17). For more details on the ports usage and jumper matrix refer to the EB2410ITX Connector and link
pinouts [http://www.simtec.co.uk/products/EB2410ITX/files/pinlist.html] document.

2.4. Real Time Clock
The Real Time Clock (RTC) is integrated into the S3C2410. The RTC has a 32KHz crystal attached. The RTC has the capacity to hold the date and time and keep them using a minimum of power, typically 3uA with 1.8V supply. There is also
the ability to set alarms which may generate interrupts, this may be used to perform repeating tasks with long intervals
without consuming large amounts of power.
2.5. JTAG
The S3C2410 and the system CPLD are connected to a single JTAG chain. The JTAG chain is available from this 0.1inch
20way connector and allows reprogramming of the user CPLD and ICE debugging of the processor. This connector has
the standard ARM Multi-ICE pinout so most JTAG debuggers will be compatible.

2.6. Memory
2.6.1. NOR boot flash
The EB2410ITX has provision for a single NOR flash device. This device typically contains the bootloader and optionally
a Linux image to boot, though it can contain anything the user requires. The flash is implemented as a single sixteen bit
wide device, which is selected by use of the nROMCS chip select from the system CPLD, nROMCS is derived from
nCS<0> and nCS<1> from the S3C2410. This memory appears read only in chip select 0 (0x00000000 to 0x01FFFFFF)
and read/write in chip select 1 (0x0C000000 to 0x0DFFFFFF) of the S3C2410 physical memory map.
Figure 2.4. NOR flash to S3C2410 attachment
2.6.2. SDRAM
The EB2410ITX has provision for four SDRAM devices with either the default 256MBit capacity or a 512MBit capacity.
This memory, where fitted, is accessed using the S3C2410 SDRAM controller and appears in banks six and seven of its
physical memory map (0x30000000 and 0x38000000).

EEPROM
2.6.3. EEPROM
There is provision for a single EEPROM connected via the I2C bus. All specification boards have an 8KBit (1KB) device
fitted as standard but up to 256KBit can be accommodated. The device is typically used to hold the non volatile settings in
the ABLE bootloader.
2.7. Super IO controller
The EB2410ITX has provision for an additional super IO controller which provides two additional 16550 type serial ports,
a full function parallel port and a full IRDA interface.
2.8. Power Supply
The board may be powered either by the standard 20 way ATX type Molex connector or the 20 way SIL 0.1inch auxiliary
power connector.
The ATX power supply must be suitable for the EB2410ITX. A supply rated for operation of 80W or less is recommended
as higher rated supplies are not stable under the very small power draw of the board.

Chapter 3. Bootloader
3.1. Overview
The Simtec Electronics Advanced Boot Load Environment (ABLE) is a portable modular boot loader for use in applications where an OS must be retrieved and started. ABLE provides extended functionality providing modules for a command
line, video consoles, serial consoles, network booting and numerous other facilities.
ABLE is a powerful tool and provides a very flexible environment useful for both development and deployment of systems. ABLE is a boot loader, not an Operating System this distinction can sometimes lead to misunderstandings about the
capabilities provided by ABLE. A boot loader in this context is a self contained program which retrieves and starts execution of an Operating System. It does not execute user programs itself (all the CLI commands are built in) and does not
provide services to an Operating System once started (PC BIOS perform this role).
The modular nature of ABLE allows the use of the same building blocks for every supported platform. The integration and
omission of various modules allow for specific driver sets depending on the peripherals of a platform. The flexibility of
this approach allows for a common familiar environment across all supported platforms while still supporting a complete
feature set.
This chapter only provides a brief introduction to ABLE. Full documentation can be found in the ABLE user guide [http://www.simtec.co.uk/products/SWABLE/files/able-set/book_userguide.html].
3.2. Getting Started
When a platform is initially powered or a hard reset performed, the ABLE environment will be started and each component module will be loaded in turn. The last module loaded is the ABLE shell, which will present the user with a command
line interface.
ABLE has the ability to use a combination of input and output sources to interact with a user. The default is to use all the
input and output devices available. For example, on the EB2410ITX both the console serial port and the video display will
be used to output and the serial port for input (future versions may support USB keyboards for input).

The input devices are controlled by using the cons-read parameter and similarly the cons-write parameter controls which
output devices are used.
Typically the console serial port is used to interact with the ABLE CLI.
Unless the boot parameters are altered from their default settings the autoboot process will commence. To manually start
an Operating System the command line must be used.
3.2.1. Using hyperterm as a serial console
To access the serial console from windows the hyperterm program can be used. Identify which serial port the platform is
connected to and ensure a note is made of the correct COM port, e.g. COM1 or COM2.

Using minicom as a serial console
Start HyperTerminal and create a new connection. When prompted for which modem to use, instead choose the appropriate COM port, as noted earlier. Then the appropriate settings for your platform (please refer to platform specific documentation) typically these settings are 115200 bits per second, 8 data bits, no parity, 1 stop bit and no flow control as shown in
Figure 3.1, “Hyperterm settings window”.
Figure 3.2. Hyperterm displaying ABLE output
Once the connection is established the output from ABLE should be seen in the hyperterm window as in Figure 3.2,
“Hyperterm displaying ABLE output”
3.2.2. Using minicom as a serial console
To access the serial console from LINUX® the minicom program can be used. Identify which serial port the EB2410ITX
is connected to and ensure a note is made of the correct device node, e.g. something like /dev/ttyS0 or /dev/ttyUSB0.

Chapter 3. Bootloader
Start minicom and ensure the correct settings are selected (Default is Ctrl-A p). These settings are 115200 baud, 8 data
bits, no parity and 1 stop bit as shown in Figure 3.3, “Minicom settings window”. Obviously Minicom should be using the
correct serial port as noted earlier.
